Check out this awesome sci-fi animated short called Dark Vessel, which is packed full of bloody robot murder, mysticism, reincarnation and revenge. The film was made by Rocky Curby, and here's the synopsis:
A hopeless romantic is caught trespassing while trying to woo a girl. Problems occur when the girl's father forces him to remove a dead man's shadow. Tragically, the romantic becomes a vessel of death.
This is such a cool film! I seriously wasn't expecting what I got when I sat down to watch this film. It's brutally violent, and the fact that it features animated robots that can bleed is really fun. Check it out!
